How WoW works.

Hi.

I have been having a problem of monsters not dropping money, but some monsters do, and some don't.

At the earlier stages of mangos, I was getting money from all monsters, but im not getting money from all monsters now i've updated.

Now someone said on the forums in one of my posts that it's suppose to be this way, that not all monsters drops money. But when you goto wow websites that has a database of the retail server stuff, and you look into monsters, all I seen is suppose to drop money.

My question is: How does it work? do all monsters drop money, and if so why aint they all dropping for me, but if it's only selected monsters in the game that does, then im fine with that.
